MinWave Metamaterial filters

MinWave designs and manufactures RF front-end solutions from C band to Ka-band. Our technology is based on a novel metamaterial filter with low insertion loss, high selectivity, high rejection, and wide stopband. Due to the metamaterial nature of the designs, the passband has a sharp roll-off with a deep level of rejection. To improve the selectivity of the pass band and/or maximize the rejection at a specific frequency, single or stack of transmission zeros can be added at the appropriate frequencies without increasing the footprint. Our filters are compatible with waveguide, and coaxial ports as well as surface mount interfaces.

Key features: ​

Nature of the technology

1. Custom bandwidth

The metamaterial nature of MinWave designs enables customizable bandwidth (1-50%) while maintaining low insertion loss and fixed total length of the filter. The typical insertion loss in wide band filters is below 0.3 dB and in narrowband filters are bellow 0.9 dB in Ku and Ka-bands.

2. Custom Selectivity  

Increasing the order of filter is obtained by adding a deep subwavelength length, e.g. few millimeters in Ku-band to the size, resulting in enhanced rejection.  

3.Transmission Zeros in small footprint

Our metamaterial designs introduce a stack of zeros on the right side of the passband, which makes sharp selectivity on the upper side. By properly engineering these transmission zeros, the selectivity of the filter in the lower side can also be engineered.
